A while back, I accidentally sent the same Slack message five times to hundreds of community members
It happened because I was relying on a fragile automation flow. One small mistake and it cascaded.
Instead of trying to patch the automation again, I decided to rebuild the workflow from scratch using AI.
I used Cursor to generate a small internal tool that:
-
Connects as a Slack bot
-
Lets me send controlled bulk messages
-
Adds simple guardrails to prevent duplicate sends
-
Includes a preview step before pushing anything live
-
Logs activity so I can trace what happened
Time to working version: about 30 minutes.
It’s not a polished SaaS product. It’s a focused internal tool built around one very specific pain point.
What stood out to me is how different the mindset feels now. A year ago, I would have searched for a tool or tried to stretch an automation platform beyond its limits. Now, if the logic is clear, I can just build the layer I need.
For those of you building products:
-
Are you using AI to create internal tools for your team?
-
Have you replaced any third party tools with small custom builds?
-
Where do you draw the line between “quick AI build” and “proper product”?
Curious how others are approaching this.
